Looking at making some changes to my 351w roller.. Need advice

Thanks for the input on the injectors. I guess I thought 30 was pushing it. I will leave those alone for now. I was looking at a comp cam last night. Part # XFI236HR-14 and NX282HR. My only concern is the fact that I am running 1.7's

Ok, I think I have somewhat narrowed down what I need for a cam but still unsure somewhat. Like I said, I currently have a stage 1 TFS cam with 1.7's. I have found a couple that will work and one I definitely like but the 1.7's will set the lift to over .600.

The cam that I do like is designed for 1.7's. XE276HR The only part that I dont know if I will notice much is that with 1.7's the overall lift isnt too far from the TFS stage 1 cam. The duration isnt too far off either. The only big difference is the rpm range. Here are specs..

It seems to me that this Comp cam wouldnt be much different than what I curretly have. The rpm range TFS 2000-5500 vs Comp Cam 2200-6200

My biggest beef with the TFS cam is that it seems to fall short around 4700 rpm. The rpm range given is for a 302 and so I would assume this would drop with a 351w
